Definitions

• the present invention relates to a cleansing cosmetic composition that has a high cleansing power for makeup, particularly, difficult-to-remove makeup such as mascara, can quickly remove makeup from the skin, is easily applicable onto the skin without dripping, etc., in use, and is washed off thoroughly.
• a cleansing cosmetic composition that has a high cleansing power for makeup, particularly, difficult-to-remove makeup such as mascara, can quickly remove makeup from the skin, is easily applicable onto the skin without dripping, etc., in use, and is washed off thoroughly.
• cleansing cosmetic compositions used in makeup cleansing are broadly classified into two: wipe-off and wash-off types.
• wipe-off type has been used in conveniently removing makeup composed mainly of oil, such as mascara or lipstick.
• the wipe-off type is a manner in which a tissue or cotton is moistened with a cleansing cosmetic composition, the melting action of which helps makeup come off, and thus, the makeup is wiped off with the tissue or cotton. Since the high melting action of oil contained in the cleansing cosmetic composition influences its makeup cleansing power, the selection of the formulated oil is important.
• a nonaqueous cleansing composition has been proposed which is formulated with isoparaffin hydrocarbon, chain dimethylpolysiloxane, and other oils (Patent Document 1).
• bases which comprise oil that is easily rinsed off. They contain 50% or more liquid oil which is formulated with a surfactant therein. Such formulations are provided with water washability such that the surfactant emulsifies the oil during washing off with water. These compositions are generally called cleansing oils. Briefly, the characteristics of the wash-off type are added to those of the wipe-off type.
• cleansing oils there have been proposed a composition comprising liquid oil, a nonionic surfactant in a liquid or paste state, and 0.1 to 2.0% by weight of water (Patent Document 2), a composition comprising a mixture of 60 to 85% by weight of a liquid oil agent and a nonionic surfactant, and 12% by weight or less of water (Patent Documents 3 and 4), etc.
• the cleansing oils are characterized in that the oil and the surfactant occupy the most part of the composition, as in the wipe-off type, and water is formulated in a small amount.
• the cleansing oils which contain a large amount of oil, are unpleasant due to an oily feel during application and are also unpleasant due to the viscosities of emulsions formed from the oil washed off with water, leaving a slimy feel on the skin.
• the cleansing oils with the composition as described above are in a liquid state having a viscosity as low as 100 mPa ⁇ s or lower, usually 70 mPa ⁇ s or lower, and therefore have presented the problem that they are difficult to apply because of dripping when put on the hand for application or running on the face during application.
• this cleansing composition cannot overcome the dripping problem seen in cleansing oils, because the composition has a low viscosity, albeit with reduced oiliness.
• this cleansing composition has also presented problems in safety or usability (e.g., sore eyes resulting from the cleansing composition that has entered the eyes), because it comprises ester or ether of a lauryl or tetradecyl group and a hydrophilic substance, lauryl alcohol, and lauric acid.
• cleansing gels in a gel state or cleansing creams in a cream state have been developed as easily applicable compositions improved in dripping.
• the cleansing gels refer to compositions whose viscosity is enhanced with an acrylic thickener, water-soluble polysaccharides, agar, a cellulose thickener, or the like to disperse oil. Based on such an approach, methods have been proposed which are intended to prevent dripping from the hand or face during application and allow a cleansing composition to easily blend into makeup (Patent Documents 6 to 9).
• the cleansing creams have a viscosity derived from an O/W-type emulsified state, which prevents dripping from the hand or face during application and allows the composition to easily blend into makeup. Therefore, to melt makeup into the oil, the emulsified state must be destroyed to release the oil. Thus, the blending into makeup takes much time, and quick removal of makeup is difficult to achieve. Moreover, they also have presented the problem that dirt in minute areas in pores or sulcus cutis on the skin is difficult to remove due to their high viscosities.
• An object of the present invention is to provide a cleansing cosmetic composition that quickly removes makeup from the skin, is easily applicable onto the skin without dripping from the hand or running on the face during application, and can freshen the skin because of being washed off thoroughly.
• the present inventors have conducted diligent studies and consequently completed the present invention by finding that a cleansing cosmetic composition that contains silicone oil and volatile hydrocarbon oil at a particular ratio, further contains dihydric glycol, polyoxyethylene glyceryl fatty acid ester, and water, and has a viscosity within a particular range can solve all the problems described above.
• the present invention provides a cleansing cosmetic composition
• a cleansing cosmetic composition comprising
• R 1 , R 2 , and R 3 represents a saturated or unsaturated higher aliphatic hydrocarbon group having 14 to 22 carbon atoms, and the other moieties each represent a hydrogen atom; and l, m, and n each represent a positive integer, and
• a cleansing cosmetic composition according to the present invention is easily applicable onto the skin without dripping from the hand or running on the face in use, and can freshen the skin because of being washed off thoroughly. Moreover, the cleansing cosmetic composition of the present invention has a high cleansing power, is less irritating (e.g., less smarting eyes), and is also excellent in its functions and safety.
• Silicone oil (component (1) described above) used in a cleansing cosmetic composition according to the present invention may be any of volatile and non-volatile silicone oils and can be selected appropriately from those conventionally used in cosmetics, etc.
• volatile silicone oil examples include: chain silicone oils (chain polysiloxanes) such as decamethyltetrasiloxane, hexamethyldisiloxane, and dodecamethylpentasiloxane; and cyclic silicone oils (cyclic polysiloxanes) such as hexamethylcyclotrisiloxane, octamethylcyclotetrasiloxane, decamethylcyclopentasiloxane, and methylpolycyclosiloxane.
• chain silicone oils chain polysiloxanes
• cyclic silicone oils cyclic polysiloxanes
• non-volatile silicone oil examples include modified silicone oils such as dimethylpolysiloxane, phenylmethylpolysiloxane, methylhydrogenpolysiloxane, polyether-modified silicone, alkyl-modified silicone, higher fatty acid ester-modified silicone, higher alkoxy-modified silicone, phenol-modified silicone, fluorine-modified silicone, and cross-linked organopolysiloxane.

• the silicone oil is formulated in an amount exceeding 15% by mass, the resulting composition is unpleasant due to a strong oily feel during blending into makeup and is not favorable in terms of feeling of residues after washing off.
• Volatile hydrocarbon oil (component (2) described above) used in the cleansing cosmetic composition according to the present invention is cyclic or linear hydrocarbon oil appropriately selected from those conventionally used in cosmetics, etc., and may be formulated alone or as a mixture.
• Non-volatile hydrocarbon oil tends to remain on the skin and does not freshen the skin after rinsing. In addition, it is not excellent in oily texture after towel dry. Thus, it is important for the cleansing cosmetic composition of the present invention to use volatile hydrocarbon oil.
• Examples of the volatile hydrocarbon oil that can be used in the present invention can include isoparaffins.
• Specific examples of the isoparaffins include light isoparaffin, light liquid isoparaffin, heavy liquid isoparaffin, liquid isoparaffin, hydrogenated polyisobutene, isohexadecane, and isododecane. Among them, isododecane and isohexadecane are particularly preferable in terms of a makeup cleansing power.

• the amount of the volatile hydrocarbon oil formulated exceeds 15% by mass, the resulting composition is unpleasant due to a strong oily feel during blending into makeup and is not favorable in terms of residues after washing off.
• compositions for example, foundation, lipstick, and mascara, often contain silicone oil and hydrocarbon oil.
• silicone oil and hydrocarbon oil for cleansing off such makeup, it is important that the composition well blends into these oil components. Therefore, the cleansing cosmetic composition of the present invention, which contains both the silicone oil and the hydrocarbon oil (volatile), is particularly effective for cleansing off such makeup.
• the cleansing cosmetic composition of the present invention has a weight ratio between the silicone oil and the volatile hydrocarbon oil (silicone oil/volatile hydrocarbon oil) that falls within the range of 0.3 to 3, more preferably 0.5 to 2. As a result, the cleansing cosmetic composition exerts an excellent makeup cleansing power. When this ratio is smaller than 0.3 or larger than 3, the resulting composition tends to have a reduced cleansing power and offer no fresh feel after rinse.
• Dihydric glycol (component (3) described above) used in the cleansing cosmetic composition according to the present invention is one or two or more selected from, but not limited to, for example, 1,3-butylene glycol, 1,4-butylene glycol, 2,3-butylene glycol, 2,3-dimethyl-2,3-butylene glycol, dipropylene glycol, and ethylene glycol.
• the dihydric glycol according to the present invention may play a role in adjusting the viscosity of the composition, mildly cleansing the skin, and stabilizing the composition.
